Scott:

The gravity of click-throughs: Click = landing experience. All clicks aren't created equal. They differentiate on who they are. Branding is always impacted. When someone lands on your page after clicking on your

ad they get an impression of business. Landing pages are more than just a page. You can get creative in design and experience including rich media, avatars, things that typically may be considered no no's in

classic landing pages. Social media interfaces and mobile optimized experiences are also valuable.

3 different ways to scale, optimize:

Test Scaling
Increase the number of alternate landing pages
a/b vs. multivariate techniques
As far as the outside world is concerned, still just one page
Diminished returns ("the wall")

Horizontal Scaling
Increase the number of distinct landing page "destinations". Landing pages that are tailored to tight messaging.

Vertical Scaling
Expand the scope of what a typical landing experience is. Microsites are an example of this. Multi-page experiences can allow you to bring in behavioral data.

All the information you know about people matters. If you give people control over the information, this will make a bigger impact. Consumers know more about what they want then you ever will.

Give the user tools to define their experience and then direct them to your site. Example was a 300x250 dockers ad that let a potential shopper customize their docker pants and once this is done they are directed

to the dockers site with these pants to purchase.

87% not satisfied with their campaign conversion rates. 60% doing no testing or optimization of any kind. Majority of those testing use only manual a/b testing.
